You're right, Mason~I looked at the name of the author, and it's by Shane Peacock~and the name of the book is "The Eye of the Crow". At the top of the cover is "The Boy Sherlock Holmes\ His 1st Case".

I've barely started it, I've been very busy with family matters~I will see if I can check the originals out from my library. As much as I love a good mystery, I can't believe I've never read the Sherlock Holmes collection!
